Tea seed episperm powder aerated concrete block and preparation method thereof

Abstract

The invention provides a tea seed episperm powder aerated concrete block and a preparation method thereof. The tea seed episperm powder aerated concrete block is prepared by the following raw materials by weight: 30-35 parts of broken block slag, 20-25 parts of fly ash, 15-18 parts of cement, 12-16 parts of lime, 2-3 parts of sodium benzoate, 15-20 parts of gypsum, 1-2 parts of aluminum powder, 20-25 parts of the tea seed episperm powder, 8-10 parts of vermiculite powder, 4-8 parts of polyvinyl alcohol, 2-3 parts of borax, 2-3 parts of waste oil, 2-3 parts of sodium persulfate, 3-5 parts of asphalt, 1-2 parts of a silane coupling agent KH570 and a proper amount of water. By adopting the tea seed episperm powder as a raw material, the weight of the aerated concrete block is lightened, and wastes can be utilized.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an aerated brick and a preparation method thereof. Background technique [0002] As a new type of wall material, aerated brick is a low-energy, environmentally friendly new building material, which belongs to the building material promoted by the state. However, because ordinary aerated concrete bricks are made of cement, fly ash, quicklime, gypsum, etc., There are problems such as large drying shrinkage, low strength, water seepage, no corrosion resistance, poor heat insulation, and single source of materials. Therefore, further research on aerated concrete brick technology is urgently needed to further meet market requirements. Contents of the invention [0003] The object of the present invention is to provide tea seed shell powder aerated brick and its preparation method, which uses tea seed shell powder as raw material and can be used as waste. [0004] Technical scheme ...
